It has become practice for most magi to put collars on their tenabre fox hatchlings, with bells attached. Although most argue against collars for intelligent creatures, it is necessary if one wants to find these young foxes. Most of the time they creep about silently, unseen to human eyes. It is only once in a while that these hatchlings forget that they are supposed to be in their shadow form. Then they flicker into sight, usually in the middle of a dining table, holding a stolen morsel of food in their mouth. Tenabre kits are some of the most unscrupulous and naughty of companions, and must be trained very well unless they run rampant.

These beasts are so cunning that their whereabouts have been unknown for centuries. Every now and again, a magi would spot one, but after pursuing it for a while, would lose track of the creature. The magi now know that this was because these foxes have the ability to slink away and simply dissolve into shadows. Though other creatures have been known to possess the same powers, tenabre foxes have used it to their full advantage, stealing chickens from villages and spying on humans. No one knew that it was tenabre foxes committing these acts – people assumed that these foxes lived far away. It was to everyone's surprise that tenabre foxes didn't live in some remote area, but lived right alongside humans, without the humans ever knowing. These smart creatures have been living alongside the humans for centuries, finding it easier and more amusing to take food than hunt for their own. Though they love to play tricks on other creatures as well, tenabre foxes find no prey as hilarious as humans. If a shoe or a sandwich is suddenly missing, and you can't seem to find it, it is usually a tenabre fox pulling one of its many pranks. Tenabre foxes find teasing humans to be the ultimate game. Naturally, people are trying to teach them to remain visible when at The Keep, but it has had little success. And one must never, never admonish one of these foxes, or it will just melt away into shadow and not reappear for a week or two, just to teach you a lesson. Only positive reinforcement works, so it is important to keep a treat or two on your person, and not to expect too much.
